PACKAGE MOLD.

My invention relates to a molding device wherein the packing of merchandise of many varieties may be accomplished to better advantage than has heretofore been possible. 5 It has particular reference where the material to be packed is enclosed in a paper wrapper,

and heretofore the use of such paper has been a source of trouble, due to it bagging and the necessity of using extra paper in order to close the ends of the package. These disadvantages have largely arisen through making the mold the size of the finished package, whereas by employing my invention only a single paper need be used and upon removal from the mold, the ends of thefin ished package may be closed either by hand or by machinery without either leaving an opening at the corners or having the paper bag at those points.

This is accomplished by making the mold approximately the required width of the finished package but having greater length this length being determined by the finished length of the package and the amount of wrapper required to close the ends.

In the open space of the mold I provide two movable blocks which, when inserted with the wrapper, fit snugly therein.

These blocks are inserted in the center portion and then drawn apart toward each end of the mold so that they serve not only to hold the paper firmly, but to give it a slight stretching in two directions and leaving a center portion of the mold enclosed in the wrapper ready to receive the n'ierchandise which is packed between the two blocks to an amount equal to the required finished sizes The wrapper is then folded over and the finished package and the sliding blocks are forced from the mold, the blocks then removed and the ends of the package closed. This results in the completed product having a smooth surface with the ends entirely closed and with the use of but a single wrapper.

Other and further advantages will. appear from the following specification and drawings.

In the drawings:

Figure 1 is a perspective view showing the molds and blocks with the wrapper inserted;

Figure 2 is a longitudinal section the center of Figure 1;

through Serial No. 99,497.

Figure 3, is a transverse section through the center of Figure 1.

In Figure 1 I show a mold which is composed in this instance of the ends 1 and 2 with side pieces 3 and 4, although this may be of any suitable construction which will provide an open center portion 5 in the mold. There are two blocks 6 and 7 which slide longitudinally in the center portion 5 of the mold and which are adapted to fit snugly when they are inserted with a wrapper 8.

By placing the paper over the mold and then taking the two blocks 6 and 7 and placing them together in the center portion of the mold, the paper is forced down to the proper depth, which gives the paper a slight transverse stretching as would be indicated in Figure 3. Then as the blocks are forced apart into the positions shown in the drawings, the same transverse stretching of the paper is retained and in addition a slight longitudinal stretching occurs for the reason that, as the blocks fit snugly in the mold, the paper cannot slide by them, but must be slightly stretched as might occur in any commonly known drawing operation in the lVhile I am aware that this invention is susccptible of many changes and variations, I desire to include all such variations within the scope of my claims.

I claim:

1. In a device of the kind. described, a

mold having a plurality of movable paper stretching means therein.

2. A mold having side and end portions with removable blocks in the open portion of the mold adapted to slide therein. h

3. A mold having an open center portion an n and removable blocks adapted to slide there in; said blocks and said open center portion being equal in depth.

4. In a, device of the kind described, a mold open on two sides and having a plumlityof slideble Wrapper retainingmeans therein.

5. In a device of the kind (leseriherjl, :1 mold having paper stretching means as; a part thereof. in

In testimony whereofi I have signed my name to this specification this 31 day of March, 1926.
